| 摘 要： | 在规模养殖户饲养的奶牛中选择年龄在4～6岁，体重、胎次、泌乳时间等基本一致的荷斯坦泌乳牛18头，根据农户的饲喂条件，分为三组，每组6头。试验A组饲喂全价配合饲料和玉米秸秆青贮，试验B组饲喂混合饲料、粗饲料和玉米秸秆青贮，对照组C组采用一般的常规饲喂(有啥喂啥)方式，观察饲喂不同日粮对奶牛产奶量的影响效果。试验结果：试验A组奶牛头均日产奶量19．82kg，个体产奶量6045kg，试验B组头均日产奶量工17．27kg，个体产奶量5267kg，对照C组头均日产奶量12．41kg，个体产奶量3785kg；试验A组和B组头均日产奶量比对照C组增加7．41kg和4．86kg，个体产奶量分别增加2260kg和1482kg。

| Abstract: | Eighteen cows at the age of 4 to 6 years old with similar body weight, parity, and lactation stages from relatively large cattle farmers were divided irtto 3 groups with 6 cows in each group to deter- mine the effects of rations on milk yield. Group A received a formulated diets and corrt silage; group B fed a mixed ration, forage and corrt silage, group C were used as a control and fed the feeds at hand. The resuits showed that the average daily milk production and milk yield for group A, B, and C were 19. 82 kg, 6042 kg; 17.27 kg, 5267 kg; and 12.41 kg, 3785 kg, respectively, the average daily milk production and milk yields of group A and B were 7.41 kg and 4.86 kg, 2260 kg and 1482 kg higher thart that of control group, respectively. |
